Application filed February 27, 1909; Serial No. $0,361.

citizen of the United States, residing at New Albany, in the county of Floyd and State of Indiana, have invented a new and useful insulator-Bracket, of which the following' is a specification.

The invention relates to improvements ininsulator brackets.

The object or" the present intention is to improve the construction of insulator brackets, designed for supporting telegraph, telephone and other electrical Wires, and capable of being quickly applied to a brick or stone wall, and of being readily .removed therefrom Without damaging the Wall.

Another object of the invention is to prof vide an insulator bracket o' this character. adapted to be readily applied to any corner ot' a building', and equipped with ineans for iirnily anchoring it tothe saine, whereby it is ei't'ectually prevented :troni being;` pulled therefrom by a light. strain, so that the (langer incident to live wires and resulting from the pulling o1, of the supporting' bracketswill be practically eliminated.

lllith these and other objects lin i'iew, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawing, and pointed out in the claims hercto appended; it being understood that various changes in the forni, proportion, size and ininor details ot construction, within the scope of the claims, may be resorted to without departing from the spirit or sacri,- ficing any of the advantages-ot the invenq tion.

In the drawing Figure l is a vertical sectional view, partly 1n elevation, ot' 'an 1nsulator bracket, constructed in accordance withthis invention. Fig. 2 is a perspective View of the liracket detached. vliip'. is a vertical sectional View partly inv elevation, illustrating a slight modification ot the iuvcntion. Fig. l is a detail perspective view of the slidable wedge, shown in Fig. l.

Fig. 8 is a vertical sectional. view, partly in Section, illustrating another form of the invention. Fig. t) is a perspective View ofthe brach-:6 illustrated in rig.' e. rief. io is s (iet-aa perspective view of the sli able wedge, shown in Figi. 8,

Lilte numerals of reerence designate corresponding parts in 'all the lgures ot the drawing:V

1 desi signed to be preferably stamped from suitable sheet inet-al to enable it to be cheaply manufactured, but it may be constructed in any other preferred manner, us will be readily understood. The bracket, which has e vertical bach or body ortion to tit against @naties an insulator bracket, de-v a well, is provided with upper and lower p 'horizontal insulator' supporting crine 2,

which in the forni of the invention illustrated in Figs. l and 2are1provided with vertically clined circular openings 3, adapted to receive a pin 4, on which a standard insulator 5 is mounted in the usual manner. The insulator 5 is in `the forni of a cap and is screwed on the upper end of the pin. As the particular construction ofthe insulator and the manner of securing the same to the upper end of the pin do not constitute a.

portion ofthe present invention, detail cle- `ration thereof is 4deemed unnecessary.

The vertical body or back of the bracket is provided at the upperportion with a latr` eral extension 6 from which depends a vertical arm 7, adapted to lit against the Wall to brace .the bracket. The bracket is also equipped with a rearwardly extending horizontal attaching' member 8, 'adapted to be introduced into a joint between twoA bricks or stones, as illustrated in l of the drawing, and cooperating with a slidable wedge- 9 to engage the bricks or stones at the joint, whereby the bracket is securely anchored to the Wall. rlie horizontal member 8 is formed integral with thevbracket, which is stamped troni a single piece of metal, the dependi arm-? bci-ugent from the central portion of the horizontal attaching member 8 prior to bending; the blanlcpinto the 'forni illustrated in A sufficient amount oi mortar or cement is removed from the joint of a wall to enable the horizontal member 8 and the slidsble Wedge to be introduced therein.' The slidable wedge is provided with aliat horizontal upper tace l0, and its lower face is beveled or inclined at the rear portion to form the wedge. The member 8 is fitted against the flat front portion of the lower face, of the wedge when the parts arc` introduced into the joint, :ind the Wedge is then drei/vn ontwarcl to carry tile tapered rear portion for-- ward and interpone the saine between the horizontal member 8 and the upper brick or stone of `the jointQ This provides s positive clamp, which is ndepted to eiectuelly orevent the bracket foin pulled ont 'nj' the strain incident to supporting; telegi 'n., tclenlione and other ele-et leal Wires.

The slidnble wed provided wi stein lil, having :i tlne ded portion l2 nted to be engaged by a not The stein .l., illustrated in Fig. el', .is thin end liet and extends through en opening lll, consisting or' :t central circular portion und side slots or extensions l5. Qi wzisner 16 is preferably interposed between tnc not und the bracket7 :nid is provided with nn opening 17, listing side slots or 'extensions 18 endcorrespondingl with the opening ll. The thin dat .shank is designed for use on buildings having pressed brick walls, where the joint is small and 'the wedge is correspondingly reduced in thickness. 1When, howevera t'ne bracket to be employed on walls having relatively wide joint e circuler opening' i9 and a round shank 2O are employed, and. tliewedge 2l. is of increased thickness. Th depend' erin 7 is out 'trom the horizontal attaching member 'not onljT for the purpose of ein.- bracing the bracket, butV also to provide e longitudinal slot or opening il, extendingrearwardly from die openings ift or 19 and. adapted to permit the shank olf the wedge to be dropped to the desired extent This Will enable ,a relatively large slmnlf. or bolt to be employed for operating the wedge when desired.
